I like 30 card shudder shaman as with finely, you can usually see all 30 cards by turn 10. Sphere is an easy card to dump to fix hand space issues, and can help prevent cards you want from entering your hand before you finley. Additionally if your gameplan is to hide shudder from disruption with finley, it allows you to control the exact turn you topdeck shudder (decktracker recommended).

I am constantly experimenting with the last 5 cards in this deck which in this list are the chain gang, 2 cult neophytes, and 2 windchills. I could see dirty rat, sleetbreaker, schooling, and primal dungeoneer package all being good replacements depending on the meta.
